.To all whom it may concern:

Be it known that we, HENRY WEINHAGEN,

of Hoboken, in the county of Hudson and State of New .J ersey, andFERDINAND KING, of New York city, in the county. and State of New York,have invented a new and Improved Thermometer Attachment for Hot l WaterWal or receptacle.

3 out in the claims.

Bags and Like Receptacles, of which the following is a full clear, andexact description.

Our invention relates to a thermometer attachment for hot water bags andlike receptacles, and it has for its object to provide a means whereby athermometer may be attached to a hot waterbag, a fountain syringe orequivalent receptacle, in such manner that a person may know at a glancethe temperature of the water contained in 'such syringe The attachmentis capable of being made to rubber or other bags or vessels used in theirrigation of wounds, &c., before, during and.

after operations, it .being highly important in manycases that the exacttemperature of the liquid contained in the vessel should be adequatelyknown before such liquid is introduced into the wound, or isemployed-for washing parts of the body.

The invention consists in the novel construction and combinationof theseveral parts, as will be hereinafter fully set forth, and pointedReference is to be had to the accompanying drawings, forming a part ofthis specification,

in which similar figures and letters of reference indicate correspondingparts in all the views- Figure 1' is a sideelevation of a fountainsyringe, the receiving receptacle of -which is illustrated as providedwith the thermometer attachment. Fig. 2 is a'vertical section takenthrough the ,fountain of the syringe, practically on the line 2-2 ofFig. 1. Big. 3 is a view similar to Fig: 1, illustrating however aslight modification in themeans employed for placing and attaching thethermometer. Fig. 4. is a section taken essentially on the line 4+4 ofFig. 8; andFig. 5 is an enlarged sectional view'of the fountain of thesyringe at thatportion where the bulb of the thermometer is introducedinto the interior of the fountain.

shown in Figs. 1, 2 and 5, a tubular extension or pocket; 10 is formedpreferably upon one sideface of the fountain of the syringe or othervessel near the lower edge thereof, the saidpooket or tubular extensionhaving direct communication with the 'interior of the fountain. In' thisevent a tubular plug 12, is

introducedinto the open end of the pocket or ,7o tubular extension, thesaid-plug being provided with a shoulder near its lower end in orderthat it may not be readily -withdrawn Q from the pocket or extension,andwith a peripherally threaded flange 13 at its upper or outer end. Thebody portion 14'of the thermometer tube B,-,is passed upward throughtheplug, the bulb C of. the tube extending preferably into the interior ofthe fountain;

and to that endthc bulb is made at an angle to the body of thethermometer tube, as is clearly shown in Fig. 5 A packing 15 is thenplaced upon the top of the flange of the plug, said packing beingprovided wit-h an opening through which the body of the thermometertube'may extend, and'a gland 16is screwed upon the flange of the plug 2,compressing the packing 15, and veffecting awater-tight connectionbetween theplug'and the body of s the thermometer tube. The bodyportion'of the thermometer tube, or that which is.ex

posed, is preferably attached to a plate 17 in any approved manner, uponwhich plate the degrees are recorded and in connection with which theindicating material of the ther-g mometer tube is read. The plate 17,may be attached to the exterior of the fountain in any approved manner,as for example, by straps extending across its upper portion, attachedto or integral with the outer face of the fountain; but usually andpreferably, a'

clip 18is attached to the-upper portion of the thermometer plate andconnected with a' ring 19, which may be an appendage to a reinforcingstrip 20, located at the upper portion 'of the fountain. y

In Figs. 3 and 4 we have illustrated a slight modification in the mannerof locating and securing the bulb to the thermometer tube. In the saidmodified form a pocket 10, is formed upon the outer .face of thefountain or other vessel, adapted to receive within it the bulb of thethermometer tube and hold the same in close contact with one sidesurface of the fountain, thebulb being'meanwhileprotected by the pocketfrom the influence of currents of air passing over or surrounding thefountain. Otherwise the attachment of the reading plate on the body ofthe thermometer tube to the outside of the fountain may be made in themanner heretofore described; or in an equivalent manner.

-' Having thus described our invention, we

claim as new and desire to secure by Letters Patent- 7 l. A water bagprovided on one side with a tubular projection or pocket to receive thethe tubular projection or pocket and having a threaded flange at itsupper end, and a gland screwing on the said flange,substantially'asdes'cribed. q

3; The combination of a water bag provided on one side "with a tubularprojection or pocket leading into the interior of the bag, a;

bulb of a thermometer, and with means for tubular plug fitting in theextension, a gland on the plug, a thermometer having its bulb made 'atanangle to the body thereof, said bulb extending through the projectioninto the interior of the bag, and-means for securing the upper end ofthe thermometer to the bag, substantially as described. v
